quran:24:19 –

Indeed, those who like that immorality should be spread ˹or publicized˺ among those who have believed will have a painful punishment in this world and the Hereafter. And Allah knows and you do not know.  

Truly those who love that indecency should be spread, by the tongue, concerning those who believe, by its being associated with them — and the ones ˹meant˺ are the band — theirs will be a painful chastisement in the life of this world, by way of the prescribed ˹legal˺ punishment for ˹false˺ accusation, and the Hereafter, by way of the Fire, as is God’s due, and God knows, that such ˹indecency˺ does not apply in their case, and you, O band ˹of accusers˺, as regards the calumny of which you spoke, do not know, whether such ˹indecency˺ took place among them.
القرآن:٢٤:١٩ –

إِنَّ الَّذِينَ يُحِبُّونَ أَنْ تَشِيعَ الْفَاحِشَةُ فِي الَّذِينَ آمَنُوا لَهُمْ عَذَابٌ أَلِيمٌ فِي الدُّنْيَا وَالْآخِرَةِ ۚ وَاللَّهُ يَعْلَمُ وَأَنْتُمْ لَا تَعْلَمُونَ  

{إن الذين يحبون أن تشيع الفاحشة} باللسان {في الذين آمنوا} بنسبتها إليهم وهم العصبة {لهم عذاب أليم في الدنيا} بحد القذف {والآخرة} بالنار لحق الله {والله يعلم} انتفاءها عنهم {وأنتم} أيها العصبة بما قلتم من الإفك {لا تعلمون} وجودها فيهم.
